Aerobic respiration= glucose + oxygen --> carbon dioxide, water and ATP energy (higher yield than anaerobic)* this process happens in the cytoplasm and mitochondrion* the stages of it includes glycolys...

We can see that x=y-1 and therefore can sub this in our first equation, to give us 3(y-1)+2y=22. If we expand the brackets we than have 3y-3+2y=22 which can be tidied up to give 5y-3=22. If we add 3 to bo...

This is because the atomic mass of an element is the sum of protons and neutrons. While the proton number is specific for an element, the neutron number can vary for different isotopes of the element. The...
